Comprehensive investigation on the luminous and energy-saving performance of the double-skin ventilated window integrated with CdTe cells

Double Skin Facades (DSFs) have the advantages of heat preservation, heat insulation, noise reduction and energy saving. Therefore, DSFs are gradually developing into a new direction of environmental protection and energy saving of the curtain wall. This article mainly introduces the technical characteristics of DSFs from two aspects: the geometric structures of the hot aisles and the ventilation modes. And this article systematically reviews more than twenty articles which have dealt with the energy performances: thermal performances and ventilation performances. The paper finishes with some conclusions: The unique structure of DSFs makes DSFs outstanding in terms of energy saving, ventilation. However, DSFs also have some shortcomings: the initial investment and maintenance costs are relatively high, the fire protection design is relatively difficult, and the industry lacks industry standards. Therefore, it is necessary to estimate the overall energy-saving effect in advance, continue to in-depth optimization research on the engineering application value of DSFs, and ultimately bring good social and economic benefits.

Double Skin

Double skin facade has been popular in China since new century. It provides challenges to deal with overheating problems in air cavity and improve energy saving effects in hot summer and cold winter climate zone in China. This paper develops a new ecological facade which includes three key elements: a ventilated double skin facade, a tillandsia usneoides plant curtain and watering. The biological characteristics especially the absorbtivity of tillandsia usneoides were analyzed via SEM scanning photographs. Bud scales and mesophyll cells of tillandsia usneoides are the main tissues to keep water. Then a method to construct an ecological double skin facade using condensation water was introduced.

Double Skin

The energy flows of the double skin, glass-glass façades have been analysed, establishing a mathematical model to determine the energy savings provided by this construction solution in 10 cities in Spain. It has been found that the two climatological variables that most influence energy savings are outdoor temperature, as it is directly related to the demand for heating, and solar irradiation, as it is the source of energy from which savings are extracted. Energy savings in winter vary between 11.1% and 20.5%, depending on the weather. A linear relationship between the annual average outdoor temperature and the useful energy provided by the double- skin façade has been determined. It was verified that the maximum energy saving occurs when the façade is offset a few degrees to the east from the pure south orientation. It deviates further east, the higher the annual average temperature. A linear relationship has been established between the outside temperature and the azimuth of the façade with which the maximum energy saving occurs. To obtain savings percentages greater than 20%, the ratio between the double-skin façade surface and the total heated surface of the building must be less than 7.

Saving Effect

In recent years, energy efficiency and energy saving strategies have become priorities for energy policy in most countries, and green energy saving buildings has attracted more attention in the worldwide. The use of passive energy saving natural ventilation strategy can improve the effect of building energy saving and improve the internal microenvironment of the building. This paper introduces and analyzes the passive preheating natural ventilation double skin facade (DSF) comprehensively. The influence of the structural parameters of the double skin facade in cold season ventilation on the preheating ventilation effect is discussed on the basis of the discussion and experiment of an actual double skin facade office building. Further, the energy-saving effect of the passive preheating natural ventilation double skin facade is simulated and verified. The effect of structural parameters of DSF in cold season on the thermal performance is summarized. These corresponding results could provide some reference for the buildings in the similar climate regions.
